I'm sure tha the hardware is working. Just need to set the program up to use it....

Can anyone help me with some kind of toturial, step-by-step, foolproof how to set this function up ? I'm using the latest version og Linuxcnc...

Hi,

Unless you deselected it when producing your config with stepconf, it is already there.

I suspect you need to read the manuals and learn what M6 does.

Hi ArcEye

Thanks for your reply.
I think your are right
Late last night I found out that it is a Gladevcp-extension I'm missing.
One that can control the proces of measuring the tool-length and return to the actual job.

It has to very simple to use and install. I don't need one with many options.
Have you any suggestions where I can find one already made?

The manual toolchange component is called hal_manualtoolchange and will be installed in /usr/bin

It appears you are talking about some other unspecified program.

There is a version of it that allows jogging whilst paused for tool change, but that does not use gladevcp

You are going to have to be specific about what you are trying to do and with what

Hi ArcEye

Okay, thanks. I'll try:

What I want is an option to use my tool-length-sensor, so I can change my tool - and the computer mesaures the new tool-length and adjust it to the right z-coordinat.
The should be some kind of setup, where I can tell the program where to find the probe/sensor, and a button somethin like: "adjusting new tool height".

I have read about the hal_manualtoolchange, but I can figure out how to get some info on the screen.

Hopefully I'm a bit more specific this time ;-)

There are very few 'new' topics.
All things come to he who googles : B)

Use the google search in the left side pane, because that searches the forum and the wikis / docs etc

There can be whatever you want, but unless someone has done it before and published it, it is down to you to implement it

theirs also this amongst others

www.probotix.com/wiki/index.php?title=Au...c_Tool_Length_Sensor

also within the examples of linuxcnc is tool-change.ngc , this has information at the top of the file as to how to link your probe switch
you may find it under the subject of remap ,

Hi ArcEye
Thanks for helping me. I'have already been reading this thread, but when changing the hal_manualtoolchange-file you've uploaded I got an error that "EMC is unknown" in line 7
I did'nt manage to figure it out and put the old file back again...

The EMC Corporatio have big scary lawyers who decided that we couldn't use "EMC" to describe the Enhanced Machine Controller.

So, a few years ago we had to change all the "EMC" in the software to "LinuxCNC".

That Python file dates back to before the change.

If you look at line 7 in the .py file you need to change "emc" to "linuxcnc"

Steen,
I think this is what you are referring to:
git.linuxcnc.org/gitweb?p=linuxcnc.git;a...ch;hb=refs/heads/2.6
It uses GladeVCP just as you said and remaps M6 to also probe the tool length (you need a sensor...). I have just battled with it myself and finally got it to do the expected operations. I ran into real time issues instead, so I have not managed to conclude my tests.
At M6, it moves to your specified tool change location and prompts you to change to the new tool. You can there click the "reference tool" button and/or "tool changed" button, which will start the probing operation and then continue processing the g-code. Not over engineered in any way, but very easy to understand and use.

/Chris
